I'd like to be able to start sounds from a specific point, so I suggest the following blocks:

play sound [ v] from (x) secs :: sound // Plays the sound from that position

play sound [ v] from (x) secs until done :: sound // Likewise, except it waits until it's finished.

play sound [ v] from (x) secs until (y) secs :: sound // Similar, but only plays up to Y seconds.

(length of sound [ v]::sound) // Reports the length of the sound in seconds. It gives something like "213.40", you can use round if you don't want that.

Where would this be useful?

• MP3 Players - You can skip forward and backward in sounds.
  
• Radios - When the user tunes in, it skips to what everyone else is hearing (based on time or Cloud Data, your choice), creating a synchronized sound, like a real radio.
  
• Time Travel Games - Imagine someone made a game similar to Braid. They could back up the music when the player reverses time.
  
• MAPs - This could benefit maps greatly by avoiding sound cutting, as shown below:
  

broadcast [Part 1 v]
play sound [Song v] from (0) secs until (33) secs :: sound
broadcast [Part 2 v]
play sound [Song v] from (33) secs until (68) secs :: sound
...

The same MAP script can be applied to other things, too.

What if the user puts in more than 60 seconds/negative seconds/non-integer seconds?
More than 60 simply seeks to wherever that is - 0m and 78s seeks to 1 minute and 18 seconds (78 seconds) in.
Negative seconds don't play the sound in reverse, they simply cause the sound to start from the beginning, like 0 or the normal play sound blocks.
Non-integer seconds simply seek with more precision, for example, 12.5 seconds.

Why no hour or minute value?
@DaSpudLord makes a good point. The base value for everything in Scratch is in seconds - the timer reports seconds, wait _ secs, etc.

What happened to the seeking blocks?
stickfiregames pointed out that sprites can play more than one sound at a time, meaning those blocks can cause glitches. However, you can use this workaround to seek:

stop all sounds
play sound from (seconds) secs until done :: sound

What about playing in reverse?
Just make a reversed copy of the sound and sync them up. Scratch has a “reverse” tool built into the sound editor, to reverse an entire sound, simply use “Select All” and then “Reverse”.

There should also be a block called

((1) mins (30) secs::operators)

which returns the time given in seconds so you can do

play sound [sound v] starting at ((2) mins (14.56) secs::operators)secs::sound

Easy workaround

Can you not say ‘wait ____ seconds’ and then ‘play/start sound’?
